Procolobus badius subspecies waldronae (Hayman, 1936) [alternate spelling]
Taxonomic Notes: This form has sometimes been considered as a possibly distinct taxon (e.g., Dandelot 1968; Groves in press), a view supported by limited preliminary molecular data (N. Ting pers. comm.). Groves (in press) corrected the name waldroni to waldronae; use of waldroni here follows Brandon-Jones et al. (2007).

Assessment Information [top]

Red List Category & Criteria: Critically Endangered A2cd ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Oates, J.F., Struhsaker, T. & McGraw, S.
Reviewer(s): Mittermeier, R.A. & Rylands, A.B. (Primate Red List Authority)
Listed as Critically Endangered as the species has undergone more than an 80% decline over the last three generations, mainly due to the effects of habitat loss and hunting. Recent attempts to collect this subspecies have been unsuccessful, and no live specimens have been observed in the wild for over 25 years. Calls of what are believed to be this animal were heard in early 2008, giving some hope that the taxon may yet persist in the wild. Further survey is urgently needed.
2000 Critically Endangered
1996 Critically Endangered
